Performance Optimization of MPI Parallel Program
Zhang Shi-liao · Ship Electronic Engineering · 2013
MPI(Message-Passing Interface)[1]is an ideal parallel programming model,which has been confirmed on distributed storage system.Because MPI is based on message passing and adopts the method of message passing to realize the communication between every node,the performance of MPI parallel program is deeply depended on the efficiency of communication.This paper puts forward a common method of optimizing MPI parallel program via the experiment on improving on the MPI parallel program of DNS twice and advancing the performance of it.
